On computers that are on a shared network your IT department can sometimes block you installing add-ons to your browser.
Please speak to your I.T. team about having a copy of Give as you Live placed on your intranet or data server, where downloading should be enabled.
You can let them know that we have a 'group policy' and they can contact us on 0800 883 8450.
Alternatively, you can encourage your staff to use the Give as you Live online store. Our online store can be accessed via any web browser and doesn't involve any downloads.
